I've been using Classcraft for about 5 years now and have worked out a lot of kinks. I thought I'd share my daily routine for management.
1) Start class with daily event
2) On the board, I keep a list of -HP and +XP for the period
3) At the end of each class, I run the timer. If the class is cleaned up by end of the timer and seated, the entire class gets 50 XP.
4) The Reckoning
At the end of each class, we assess the board. Those that have -HP can only be healed or protected IF THEY MADE AMENDS to their guild. Otherwise, they take the hit. Amends means the offender helps someone such as putting away their laptop.
If there are NO HITS among Guild members, then the guild members get 110 XP (this creates herd mentality of everyone needing to behave, it is higher than collaborative XP gained in my set up).
